reduce()

void Dtk_mesh::reduce

(

)

Reduce memory cost of the Dtk_mesh, to call after adding all geometry.

The Dtk_mesh class hold internal containers that keep more memory not to reallocate each data enqueuing (like reserve of a std::vector)

This function remove all reserves to free some useless memory

set_texcoords()

int Dtk_mesh::set_texcoords	(	Dtk_Size_t	inPos,
		Dtk_Float32	inU,
		Dtk_Float32	inV
	)

Set texture coords to a point (if vertex format includes tex coords)

Parameters

inPos	: indice in the vertices array
inU,inV	: U,V to set

Returns

return 0 if ok, 1 if error, 2 if wrong vertex format

set_vertex()

int Dtk_mesh::set_vertex	(	Dtk_Size_t	inPos,
		const Dtk_pnt *	inVertex,
		const Dtk_dir *	inNormal = NULL,
		const Dtk_RGB *	inColor = NULL,

		Dtk_Float32	inV = 0.,
		Dtk_Float32	inUBrep = 0.,
		Dtk_Float32	inVBrep = 0.
	)

Set a vertex.

Parameters

inPos	: indice in the vertices array
inVertex	: vertex to set
inNormal	: normal to set (if vertex format includes normal)
inColor	: color to set (if vertex format includes color)
inU,inV	: texture coords (if vertex format includes tex coord)
